I wrote this little root utility for myself to help consolidate and automate some root functions that are available in various other apps, but nowhere all together.

Note: this utility does NOT root your Android™ device--it assumes that your device is already rooted.

If you have problems or issues with the app, please contact me via scary.alien@gmail.com with as much detail as you can provide.

FEATURES:

* display current root and device state/status

* reboot options (normal, recovery, bootloader)

* power off device

* remount rootfs (/) and/or /system in read-write or read-only mode; note: remount behavior changed in Android™ 4.2 and higher that causes remount effect to not be usable by apps other than the one that initiated the remount

* small (<25mb) partion backup function now supported in v3.9; note: this is NOT meant as a Nandroid backup replacement, but for use in backing-up small, critical partitions that to assist with device recovery; also note that a restore function is NOT included since the target partition is likely to still be open/mounted; useful for backing-up special partitions like EFS.

Warning / disclaimer: the author of this app is not responsible for any loss or damage caused by or related to its use.

If you are not comfortable with or knowledgeable about the proper use and functionality of this app, please discontinue its use and uninstall.

Just installed this on rooted stock Asus Zenfone 6 for the sake of " save or restore root privilege options" but there's no way to test whether it will restore root or not until phone needs system updates . Hope it works.
